We are an on-demand (Uber of X) startup service. We have about 10-12 competitors in our space. We are two co-founders that are new to the startup world/entrepreneurship with limited resources. We are at the idea stage with a bit of a social media following.
The info you gave isn't really enough to say whether you will be successful or not. It does sound like you may not be up for the challenge given how far you view your competitors are ahead of you, so that might be your gut feeling saying you don't want to continue.
If you think you can build a better product than what's out there then definitely continue!
